Filed Deo. 5, 1928 Patented Jan. 7, 1930 traina PATENT FFCE WILLIAM C.BURRELL, F IHLN'LK.AKI'ifIElj ILLINOIS PARTITION STRIP FOR CONCRETEApplication filed December This invention relates to improvements inparting devices for cement and concrete structures with particularreference to roadways and the like7 whereby the roadway or structure maybe caused to separate along defined planes orsections in such a mannerthat adjacent surfaces of the separated material may be permitted tointerfit one another through the parting strip when the l0 separatedportions of the roadway expand due to temperature changes.

It is an object of this invention to provide an improved parting stripfor concrete roadways and the like, said parting strip being constructedof a foraminous material to permit projecting portions on one surface ofa divided section to project through the foraminous material intoregistering cavities in the opposite section of the material.

Itis also an object of this invention to provide a parting stripconstructed of a foraminous material to permit separated sections of aroadway or the like to interflt one another through the parting strip.

It is a further object of this invention to provide a roadway partitionstrip constructed of a foraminous material and having engaged thereonapertured plate connectors through which supporting pins may be engagedfor mounting the partition strip inplace on a roadbed with the upperedge of the partition strip adapted to be located either flush with theupper surface of the road or a slight distance therebelow, as desired.

It is furthermore an object ofvthis invention to provide a roadwaypartition strip constructed of a foraminous material having mountingplates and reinforcing members engaged thereon to facilitate mounting ofthe partition strips in position on a roadbed, so that a roadway may becaused to part along a defined plane in such a manner that portionsprojecting from one section of the separated roadway will be permittedto inove back into the cavities from'which they have been separated inthe opposite section of the roadway, through the openings in theforaminous part-ition strip.

It is an important object of this invention Y 59 to provide a concreteroadway or the like 3, 1928. Serial No. 323,354.

with improved partition or dividing strips which are constructed of wiremesh, apertured sheet metal, expanded metal, or the like, to afford anarrangement whereby the roadway may be caused to separate along adefined plane in such a manner that adjacent surfaces of separatedsections will be permitted to intert with one another through theforaminous partition strip when the separated sections of the roadwayare expanded due to temperature changes.

Other and' further .important objects of this invention will be apparentfrom the disclosures in the accompanying drawings and the followingspecification.

This invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described.

On the drawings;

Figure lis a fragmentary perspective view of a partition strip embodyingthe principles of this invention and illustrating a reinforcing sleeveand also a combination supporting bracket and connector whereby thepartition strip may be supported in position and also be connected toanother partition strip.

Figure 2 is a sectional view taken on line II-II of Figure l. i

Figure 3 is a fragmentary transverse sectional view taken through apartition strip and a portion of a roadway illustrating the virregularlydefined crack caused by the partition strip through which portions ofeach of l the adjacent surfacesl of the divided sections are adapted toproject and interlit in the cor- Y responding recesses in the oppositesection.

Figure 4 is an enlarged fragmentary detailed sectional view taken online IV-IV of Figure 2, illustrating the interfitting connectingrelation between the two partition strips.

Figure 5 is a fragmenary sectional view similar to that illustrated inFigure 4, but illustrating modified forms of connecting bracket platesconstructed to permit two partition strips to be connected in alignmentwith one another.

As shown on the drawings z The partition strip in the embodimentillustrated comprises a long framework 1 constructed of wire or rodmesh, the upper and lower longitudinal rods 2 of which are slightlyheavier or of greater diameter than the remaining members of the mesh.rlhe mesh frame 1 may be cut in any desired length and is of a height orwidth substantially corresponding to the thickness of the upper layer ofconcrete which forms the roadway above the roadbed.

Y trated in Figure l. Each of the walls of the V-shaped channel section-l is provided with an aperture or opening 6 to permit a mounting orretaining pin 7 to be projected downwardly through the openings 6ydriven into the roadbed to hold the parting strip mounted in asubstantially vertical position upon the roadbed to be imbedded inconcrete or the like. l

The parting strip may be mounted so that theupper longitudinal edge ispositioned a slight distance below the upper finished surface of theconcrete -roadway, or, if desired, the upper longitudinal rod 2 of theframework may be positioned so that the rounded portion thereof is flushwit-litlie upper surface of the roadway. Y

' Vhenever desired, or when necessay, the upper longitudinal bar Q maybe reinforced by engagin' over the top thereof a longitudinally splitreinforcing pipe or sleeve 8, which extends to within a short distanceof the bracket or supporting members engaged on the end of theframework.

The part-ing strips are furnished in standard or required lengths andare adapted to be positioned vertically upon a roadbed in locationswhere it is desired to have 'the roadway split or cracked as a result ofvariations intemperatnre to which the roadway is subjected. rlhe partingstrips are arranged to be aligned with one another with the projectingends of the upper andllower longitudinal j rods 2 atone end of aframework, adapted to be inserted into the sleeves or collars 3 of apartition or supporting bracket member 4 5 engaged on an adjacent end ofVanother framework 1, as illustrated in Figure 1. It will thus be notedthat any number of the mesh frameworks l may be connected in alignmentin any desired position on a roadbed and thevarious frameworks may besupported in vertical position by means of the retaining pins 7. Theparting strips may be disposed longitudinally of a road or transversely,or both if desired, or in any other location where it may be deemednecessary to cause the roadway to crack or split to compensate for thecontraction and expansion of sections of the roadway due to temperaturechanges. j

t will be noted that the brackets or connecting members are adapted tobe positioned to connect two adjacent ends of two aligned frameworks 1.In cases whe'reit is desired to reinforce the upper members 2 of theframeworks, the reinforcing sleeves or pipes 8 may be engaged on theupper members of the frameworks, as illustrated in Figure 1.

l/Vhen a series of frameworks 1 are supported in position by means ofpins 7 upon a roadbed, the various partition strips are imbedded inconcrete or other simi-lar material, permitting the larger particles vormembers forming the concrete to project through and fill the meshopenings provided in the various frameworks. After a roadway has beenconstructed and has properly set, the parting strips tend to insure theroadway splitting or crackingvalong the planes of the parting strips, asillustrated in Figure 3, so that stones or other solid portions formingpart of the concrete on one side of a partition strip areV adapted to bepulled out of pockets or sockets formed in the concrete on the oppositeside of a partitionstrip, so that the projections on one side and theapertures Aor openings on the other side of a partition strip arecomplemental to one another, thereby permitting the same to interfit oneanother at substantially the saine points or locations when the concreteforming the roadway expands due to increased temperature changes.

In Figure 5 of the drawings, the parting strips or frameworks ,areconstructedA similar to that illustrated in Figure l, said partingstrips are 'connected by means of modified forms of connectors orsupporting brackets 9, the middle portions -of which are provided withapertured V cross-sectioned portions similar to the sections 1l. Theconnecting bracket 9 at one end of a framework 1 is provided with halfsleeves or collars 10, permitting the ends of the upper and lower rods 2to project through the short sleeves 10 and into the projecting ends oflong sleeves 11 which are formed on the upper and lower ina-rginsiof asecond supporting or connecting bracket 9 engaged on 'the adjacent endof a second parting strip as illustrated. In this construction, it willbe notedrthat two bracket plates 9 are adapted to abut one another atthe intersect-ing ends of a pair of parting strips and the longprojectingsleeves 1l of one of said brackets are adapted to be engagedover the projecting ends of upper and lower rods of an adjacentframework until the ends of the long sleeves abut against the outer endsof the short sleeves 10 of an abutting supporting bracket.

The supporting or connecting brackets 9 Y are adapted to be secured inplace by means of pins similar to the arrangement shown in Figure l sothat the connected parting strips are rigidly secured in desiredpositions upon a roadbed ready to be imbedded in concrete or the likewith the upper margins or edges of the frameworks or parting stripsposi# tioned either below the top of the roadway or flush with the uppersurface of the roadway as specifications may require.

While a wire or rod mesh or screening has been described in connectionwith Figures l sections expand due to temperature changes.

Attention is also called to the fact that if desired the parting stripsmay be constructed of expanded metal of any desired design to eectresults similar to those described in connection with wire mesh orapertured sheet metal. By providing the improved foraminous material forconstructing parting strips for roadways and the like, it will beparticu* larly noted that when sections of the roadway are cracked orsplit due to contraction of the material, that such sections maysubstantially always be expanded into interfitting relation with oneanother in substantially the same relation as they originally possessedbefore the cracking or splitting of the roadway took place. Thisimproved condition serves to hold the different sections of the roadwayin proper location and prevents creeping or displacement of crackedsections.

While the connecting plates or supporting brackets of the device havebeen described as constructed of sheet metal, such metal may beperforated if desired, or the connecting brackets may be constructed ofwire mesh or of expanded sheet metal as desired.

Each of the foraminous framework sections also has engaged thereonintermediate sheet metal brackets 12, the offset portion of each ofwhich is provided with an opening 13 to permit a horizontal bar or rodto be projected therethrough if desired.

It will of course be understood that many changes may be made andnumerous details of construction may be varied through a wide rangewithout departing from the principles of this invention, and it istherefore 'not purposed limiting the patent granted hereon, otherwisethan necessitated by the scope of the appended claims.
